CUTTER-HE AD.

Specification of Letters Patent.

Patented July 6, 1909.

App1ication filed October 14, 1908. Serial No. 457,726.

To all whom it may concern:

Be it known that I, OTIs LEE Srsoon, a citizen of the United States,residing at Malden, in the county of Dunklin and State of 5 Missouri,have invented certain new and useful Im rovements in Cutter-Heads, ofwhich the fol owing is a specification, reference being had therein tothe accompanying drawmg.

My invention is directed to the production of a cutter head i' or goringveneer blanks, and one of the objects of the invention is to provide acutter head having cutters arranged to produce V shaped gores.

Another object of the invention is the provision of means for whittlingthe gores in the barrel blanks.

Still another object contemplated by the invention is to providedetachable knives in order that the same may be readily removediorlplurposes of sharpening or renewal.

e V shaped gores are formed in the bar rel blanks by a plurality ofknives or cutters carried by a rotary head, the said knives taperinglongitudinally from their lower base ortion to the outer extremitynearly to a eather ed p e, so that the point of all the cutters of eachhead will meet in the same plane in a line which determines the angle ofthe gore being cut and terminates the gore with a sharp angle. Thewhittling action of the knives may be brought about by utilizingstraight knives in conjunction with a swin ing table adapted to moveapproximate y tangential with the cutter head; b providing a pluralityof angularl deflected knives, or a plurality of straight nives insertedin the ead at a slight angle, in the latter two cases the adjustment ofthe head being commensurate with the deflection of the knives so thateach of said knives by virtue of such adjustment will have its maximumwhittling action.

With these and other objects in view, the preferred embodiment of myinvention resides in that construction and arrangement of partshereinafter described, illustrated in the accompanying drawings, andembraced within the scope of the appended claims.

In said drawings :F1gure I is a perspective view of a pair of cutterheads mounted in operative relation to a barrel blank. Fig. II is a sideelevation of one of the cutter heads. Fig. III is an end elevation ofone of the cutter heads, and Fig. IV is a detail view of one of theangular knives.

The head comprises a pair of disks designated by numerals 5 and 6 anddetachably secured together by any suitable fastening means, such forexample as the screws (7). Referring articularly to Fig. I of thedrawings, it wilIbe noted that each of the disks is provided withrecesses (8) extending inwardly for a short distance from the periphcryof the disks and radiating from the cen ter, the said recesses beingarranged alternately and equidistantly on obverse sides of the head,considered as an entirety, and having a slight continuity of depth inthe opposite disk, so that when the knives (9) are introduced into therecesses and secured by the nut and bolt (10) they will be positioned medially of said head. Each of the knives tapers longitudinally from apoint proximate the inner end thereof to its outer distal end and abeveled cutting edge (12). hen the several knives are fastened to thehead the cutting edges are disposed alternately to the right and left ofsaid head, and in end elevation, as exhibited in Fig. III, are instaggered relation to one another.

The knives illustrated in Fig. I of the draw ings are straight knivesand are mounted concentrically wlth respect to the head, the latterbeing arranged below the line of movement of the barrel blank (13). InFig. II, I have shown another method of mounting the knives relativelyto the head. In this latter case I utilize straight knives eonjunctivelyWith recesses arranged eccentrically of the head. The same result ma beattained by maintaining the concentrica ly disposed slots and combiningknives, the type of which is disclosed by Fig. IV of the drawings, theblade thereof being disposed at a slight angle relatively to the baseportion.

In practice, any number of cutter heads are mounted upon a suitableshaft, as 14, in operative adjacency to any type of swing feed, it notbeing deemed necessai to show said feed as my invention resides a one inthe cutter head. While I propose to employ a lurality of cutter heads 1nconnection wit a swinging table in order that the required num er ofgores may be simultaneously formed in the barrel blank, it is obviousthat the single cutter head and an appropriate and is provided with astraight edge (1U feed may be used in lieu thereof for consecutivelyforming the gores in said blank. As the cutter heads are rotated and theswinging feed table manipulated the blades, owing to their particulararrangement or disposition will e caused to subject the blank to awhittling action, and owing to the longitudinal tapering feature and opositely arranged cutting edges of the knives the V- sha ed gores areformed, it being of course un erstood that the knives are so accuratelyadjusted that the extreme point of each knife strikes identically in thesame place, and as the blank is forced against the knives the lattercuts from each side of the ore and ar widened until the desired depthand wild is secured, the gores tapering to a fine point toward thecenter of the bilge of the barrel.

My invention will be appreciated by those skilled in the art owing tothe sim l oity of arrangement and construction an the facility andrapidity with which it may be op erated to perform its recitedfunctions.

What is claimed as new is 1. In a device of the character described, thecombination of a head having a lurality of longitudinall taperingknives, t e ed es of the adjacent linives converging Qutwar ly towardthe center lane of the head.

2. In a device 0? the character described, the combination of a rotaryhead and longitudinally tapering knives arranged thereon with theircutting edges dis osed lternately to the right and left of said cad, t eedges of the adjacent knives converging outwardly toward the center"lane of the head.

3. In a device 0 the character described, the combination with a headand longitudinally tapering knives arranged alternately on oppositesides thereof, the cutting edges of said knives being dis osedalternately to the right and left of sai head, the ed es of the a jacentknives converging outward ytoward the center lane of the head.

4. In a evice of the character described, the combination of a rotaryhead comprising a pair of disks, recesses arranged alternately on theouter op .osite faces of said disks, and knives detacha l secured Insaid recesses media 1y of said disks.

5. n a device of the character described, the combination of a rotaryhead comprising a pair of disks, recesses arranged alternately on theouter op osite faces of said disks, said recesses extenriin into the 0posite disks, and knives detac ably secure( in said recesses medially ofsaid disks.

In testimony whereof I hereunto afiix my signature in presence of twowitnesses.
